Differences in Micro Leaks Between Cement Iomet Glass Modification of Resin and Alkasit in Class V Restoration

Introduction

Class V restoration in dentistry is a complex procedure that often faces its own set of challenges. One of the main issues associated with Class V restorations is the position of the gingival margin, which is located in dentin or cementum. This can lead to suboptimal marginal adaptation, thereby increasing the risk of micro leakage in the restoration. Micro leakage is a significant concern in dentistry as it can lead to secondary caries, pulpitis, and other complications. Therefore, it is essential to identify the most effective materials and techniques for achieving better results and reducing the risk of micro leakage.

Background

Glass ionomer cement (GIC) modification of resin and alkasit are two commonly used materials in Class V restorations. However, the effectiveness of these materials in reducing micro leakage is still a topic of debate. The use of an adhesive system in conjunction with these materials has been shown to improve the bond strength and reduce micro leakage. However, the impact of the adhesive system on micro leakage is still unclear. This study aims to investigate the differences in micro leakage between GIC modification of resin and alkasit with and without an adhesive system in Class V restorations.

Methods

In this study, 30 maxillary premolar teeth were prepared by Class V cavity and divided into three treatment groups. The first group used a resin modified glass ionomer cement, the second group used alkasit with an adhesive system, and the third group used alkasit without an adhesive system. The samples were then immersed in a saline solution for 24 hours before undergoing a thermocycling process consisting of 200 rounds between 5°C and 55°C for 30 seconds. Micro leakage was evaluated using a 2% methylene blue solution, and the samples were observed under a stereomicroscope with an enlargement of 20x. The score for the length of penetration of dye was set from 0 to 3.

Results

The results of this study showed a significant difference in micro leakage between the three treatment groups based on the analysis of the Kruskal-Wallis test. Furthermore, the Mann-Whitney test indicated a significant difference between the first and second groups, as well as the second and third groups, both on the edge of the junction enamel and the edge of the dentin junction. However, there was no significant difference between the first and third groups (P> 0.05) in the two junctions.

Discussion

The findings of this study suggest that alkasit applied to the adhesive system has the lowest level of micro leakage compared to GIC modification of resin and alkasit without an adhesive system. These results provide important insights for the practice of Class V restoration, highlighting the importance of the selection of materials and adhesive techniques in achieving better results and reducing the risk of micro leakage. The use of an adhesive system in conjunction with alkasit has been shown to improve the bond strength and reduce micro leakage, making it a more effective material for Class V restorations.

Conclusion

In conclusion, this study has shown that the use of an adhesive system in conjunction with alkasit is more effective in reducing micro leakage compared to GIC modification of resin and alkasit without an adhesive system. These findings have important implications for the practice of Class V restoration, highlighting the need for careful selection of materials and adhesive techniques to achieve better results and reduce the risk of micro leakage. Further research is needed to explore the influence of other factors that may contribute to micro leaks in dental restoration.

Recommendations

Based on the findings of this study, the following recommendations can be made:

The use of an adhesive system in conjunction with alkasit is recommended for Class V restorations to reduce micro leakage.
GIC modification of resin and alkasit without an adhesive system should be used with caution, as they may not provide the same level of protection against micro leakage.
Further research is needed to explore the influence of other factors that may contribute to micro leaks in dental restoration.
Dental practitioners should be aware of the importance of selecting the right materials and adhesive techniques to achieve better results and reduce the risk of micro leakage in Class V restorations.

Limitations

This study has several limitations that should be considered when interpreting the results. Firstly, the sample size was relatively small, and further research is needed to confirm the findings of this study. Secondly, the study only investigated the use of GIC modification of resin and alkasit, and further research is needed to explore the use of other materials in Class V restorations. Finally, the study only evaluated micro leakage, and further research is needed to explore other outcomes, such as bond strength and marginal adaptation.

Future Directions

Further research is needed to explore the influence of other factors that may contribute to micro leaks in dental restoration. Some potential areas of research include:

The use of other materials in Class V restorations, such as composite resins and ceramic materials.
The impact of different adhesive systems on micro leakage.
The influence of other factors, such as tooth preparation and restoration design, on micro leakage.

By exploring these areas of research, we can gain a deeper understanding of the factors that contribute to micro leaks in dental restoration and develop more effective strategies for reducing micro leakage and improving the long-term success of Class V restorations.
